## /CLAUDE.md
# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Development Commands
- **Start development server**: `pnpm dev` - Starts Vite dev server with HMR
- **Build for production**: `pnpm build` - TypeScript compilation followed by Vite build
- **Lint code**: `pnpm lint` - Run ESLint on the codebase
- **Preview build**: `pnpm preview` - Preview the production build locally
- **Add Shadcn/ui components**: `pnpm dlx shadcn@latest add <component-name>` - Add specific components
## Architecture Overview
This is a React + TypeScript + Vite project with modern UI tooling:
- **Build System**: Vite with React plugin and Tailwind CSS 4 integration
- **Language**: TypeScript with strict configuration using project references
- **UI Framework**: React 19 with functional components and hooks
- **Styling**: Tailwind CSS 4 with Shadcn/ui component library
- **Icons**: Lucide React icons (integrated with Shadcn/ui)
- **Linting**: ESLint with React-specific rules and TypeScript integration
- **Package Manager**: pnpm (evidenced by pnpm-lock.yaml)
## Project Structure
- `src/App.tsx` - Main application component
- `src/main.tsx` - Application entry point
- `src/index.css` - Global styles with Tailwind imports and CSS variables
- `src/lib/utils.ts` - Utility functions (includes cn helper for class merging)
- `components.json` - Shadcn/ui configuration file
- `vite.config.ts` - Vite configuration with React plugin, Tailwind, and path aliases
- TypeScript uses project references with separate configs for app and node environments
## Key Configuration Notes
- Uses ES modules (`"type": "module"` in package.json)
- TypeScript project references split between `tsconfig.app.json` and `tsconfig.node.json`
- Path aliases configured: `@/*` maps to `./src/*`
- Shadcn/ui uses "new-york" style with neutral base color
- **Tailwind CSS v4.1.13**: Latest version with CSS-first configuration using `@theme` blocks
- **Zero-config setup**: No `tailwind.config.js` or `postcss.config.js` needed
- Uses `@tailwindcss/vite` plugin for optimal Vite integration
- No test framework currently configured
## UI Component Library
- **Tailwind CSS v4**: CSS-first configuration with `@theme` blocks
- **Vite Integration**: Uses `@tailwindcss/vite` plugin for better performance
- **Theme system**: Built-in light/dark mode support via CSS variables and `oklch()` colors
- **Shadcn/ui**: Modern React components built on Radix UI primitives
- **Icons**: Lucide React icons integrated throughout components
## Tailwind CSS v4 Features
- **Simplified setup**: Single `@import "tailwindcss"` line in CSS
- **CSS-first config**: Define themes using `@theme` and `@theme dark` blocks
- **Modern colors**: Uses `oklch()` color space for better color consistency
- **Zero dependencies**: No need for PostCSS configuration or external config files
- **Better performance**: Native Vite plugin integration

## /INTERNATIONALIZATION.md
# FlyCut Caption 国际化指南
## 概述
FlyCut Caption 组件现在支持类似 Ant Design 的国际化方式，提供完整的多语言支持和自定义语言包功能。
## 特性
- ✅ **内置语言包**：中文 (zh-CN)、英文 (en-US)
- ✅ **自定义语言包**：支持用户导入自定义语言
- ✅ **动态语言切换**：运行时切换语言
- ✅ **TypeScript 支持**：完整的类型定义
- ✅ **语言包管理**：注册和管理多个语言包
- ✅ **热切换**：无需重新渲染即可切换语言
## 基本使用
### 1. 导入内置语言包
```typescript
import { FlyCutCaption, zhCN, enUS } from '@flycut/caption-react'
function App() {
return (
<FlyCutCaption
config={{ language: 'zh' }}
// 语言包会自动根据 language 配置选择
/>
)
}
```
### 2. 使用自定义语言包
```typescript
import { FlyCutCaption, type FlyCutCaptionLocale } from '@flycut/caption-react'
// 创建自定义语言包
const customLocale: FlyCutCaptionLocale = {
common: {
loading: '読み込み中...',
error: 'エラー',
// ... 其他翻译
},
components: {
fileUpload: {
dragDropText: 'ビデオファイルをここにドラッグ',
// ... 其他翻译
},
// ... 其他组件翻译
},
messages: {
// ... 消息翻译
}
}
function App() {
return (
<FlyCutCaption
config={{ language: 'ja' }}
locale={customLocale}
/>
)
}
```
### 3. 动态语言切换
```typescript
import { useState } from 'react'
import { FlyCutCaption, zhCN, enUS } from '@flycut/caption-react'
function App() {
const [language, setLanguage] = useState('zh')
const [locale, setLocale] = useState(undefined)
const handleLanguageChange = (lang: string) => {
setLanguage(lang)
switch (lang) {
case 'zh':
setLocale(zhCN)
break
case 'en':
setLocale(enUS)
break
case 'ja':
setLocale(customJaLocale)
break
default:
setLocale(undefined) // 使用默认语言包
}
}
return (
<div>
<button onClick={() => handleLanguageChange('zh')}>中文</button>
<button onClick={() => handleLanguageChange('en')}>English</button>
<button onClick={() => handleLanguageChange('ja')}>日本語</button>
<FlyCutCaption
config={{ language }}
locale={locale}
onLanguageChange={handleLanguageChange}
/>
</div>
)
}
```
## API 参考
### FlyCutCaptionProps
新增的国际化相关属性：
```typescript
interface FlyCutCaptionProps {
// ... 其他属性
/** 自定义语言包 */
locale?: FlyCutCaptionLocale
/** 语言变化回调 */
onLanguageChange?: (language: string) => void
}
```
### FlyCutCaptionLocale
完整的语言包类型定义：
```typescript
interface FlyCutCaptionLocale {
common: {
loading: string
error: string
success: string
// ... 更多通用翻译
}
components: {
fileUpload: {
dragDropText: string
selectFile: string

videoLoaded: string
videoLoadFailed: string
// ... 更多视频操作消息
}
general: {
operationSuccess: string
operationFailed: string
// ... 更多通用消息
}
}
}
```
## 导出的语言包
### 内置语言包
```typescript
import { zhCN, enUS, defaultLocale } from '@flycut/caption-react'
// zhCN - 简体中文语言包
// enUS - 英文语言包
// defaultLocale - 默认语言包（等同于 zhCN）
```
### 语言包管理
```typescript
import { LocaleProvider, useLocale, useTranslation } from '@flycut/caption-react'
// LocaleProvider - 语言包提供者组件
// useLocale - 语言包管理 Hook
// useTranslation - 翻译函数 Hook
```
## 高级使用
### 语言包注册
```typescript
import { LocaleProvider } from '@flycut/caption-react'
function App() {
return (
<LocaleProvider
language="ja"
locale={customJaLocale}
onLanguageChange={(lang) => console.log('Language changed:', lang)}
>
<FlyCutCaption />
</LocaleProvider>
)
}
```
### 嵌套语言包使用
```typescript
const { t, setLanguage, registerLocale } = useLocale()
// 使用翻译函数
const text = t('common.loading') // "加载中..."
// 注册新语言包
registerLocale('fr', frenchLocale)
// 切换语言
setLanguage('fr')
```
## 最佳实践
### 1. 语言包组织
建议将语言包文件单独组织：
```
src/
locales/
zh-CN.ts
en-US.ts
ja-JP.ts
index.ts
```
### 2. 按需加载
对于大型应用，可以考虑按需加载语言包：
```typescript
const loadLocale = async (language: string) => {
switch (language) {
case 'ja':
return (await import('./locales/ja-JP')).default
case 'fr':
return (await import('./locales/fr-FR')).default
default:
return undefined
}
}
```
### 3. 类型安全
始终使用 TypeScript 类型定义：
```typescript
import type { FlyCutCaptionLocale } from '@flycut/caption-react'
const myLocale: FlyCutCaptionLocale = {
// TypeScript 会提供完整的类型检查和自动补全
}
```
## 与 Ant Design 的对比
| 特性 | Ant Design | FlyCut Caption |
|------|------------|----------------|
| 导入方式 | `import zhCN from 'antd/locale/zh_CN'` | `import { zhCN } from '@flycut/caption-react'` |
| 使用方式 | `<ConfigProvider locale={zhCN}>` | `<FlyCutCaption locale={zhCN}>` |
| 动态切换 | ✅ 支持 | ✅ 支持 |
| 自定义语言包 | ✅ 支持 | ✅ 支持 |
| TypeScript | ✅ 完整支持 | ✅ 完整支持 |
| 嵌套翻译 | ✅ 点分隔路径 | ✅ 点分隔路径 |
## 示例项目
参考 `test-app` 目录中的完整示例，演示了：
- 内置语言包使用
- 自定义语言包创建
- 动态语言切换
- 回调函数处理
- TypeScript 类型安全
运行示例：
```bash
cd test-app
pnpm install
pnpm dev
```
## 迁移指南
如果你正在从旧版本迁移到新的国际化系统：
### 旧版本
```typescript
// 旧版本需要用户配置 i18next
import i18n from 'i18next'
// ... 复杂的 i18n 配置
<FlyCutCaption />
```
### 新版本
```typescript
// 新版本直接导入语言包
import { FlyCutCaption, zhCN } from '@flycut/caption-react'
<FlyCutCaption locale={zhCN} />
```
新版本的优势：
- 🎯 **零配置**：无需配置 i18next
- 🔄 **即插即用**：直接导入使用
- 🎨 **类型安全**：完整的 TypeScript 支持
- 🚀 **性能优化**：内置语言包管理
- 🔧 **灵活扩展**：支持自定义语言包

function YourComponent() {
const showSuccess = useShowSuccess();
const showError = useShowError();
const showWarning = useShowWarning();
const showInfo = useShowInfo();
const handleSuccess = () => {
showSuccess('操作成功', '数据已保存');
};
const handleError = () => {
showError('操作失败', '请检查网络连接');
};
// ...
}
```
### 2. 高级用法
```typescript
import { useShowToast, useAddMessage } from '@/stores/messageStore';
function YourComponent() {
const showToast = useShowToast();
const addMessage = useAddMessage();
// 带操作按钮的Toast
const showToastWithAction = () => {
showToast({
type: 'warning',
title: '存在未保存的更改',
content: '确定要离开此页面吗？',
duration: 0, // 不自动关闭
action: {
label: '保存并离开',
handler: () => {
// 执行保存操作
console.log('保存数据...');
}
}
});
};
// 持久化消息（在消息中心置顶显示）
const addPersistentMessage = () => {
addMessage({
type: 'info',
title: '系统维护通知',
content: '系统将于今晚12点进行维护，预计持续2小时',
persistent: true,
action: {
label: '了解详情',
handler: () => {
// 跳转到详情页
}
}
});
};
}
```
### 3. 获取消息状态
```typescript
import { useMessages, useUnreadCount } from '@/stores/messageStore';
function MessageStatusComponent() {
const messages = useMessages();
const unreadCount = useUnreadCount();
return (
<div>
<p>总消息数: {messages.length}</p>
<p>未读消息: {unreadCount}</p>
</div>
);
}
```
## 消息类型
- **success** 🟢: 成功操作（绿色）
- **error** 🔴: 错误信息（红色）
- **warning** 🟡: 警告提示（黄色）
- **info** 🔵: 一般信息（蓝色）
## 已集成的功能
### ASR 面板
- ✅ 模型加载成功/失败提示
- ✅ 语音识别完成通知
- ✅ 错误状态提醒
### 待集成的组件
- [ ] 文件上传成功/失败
- [ ] 视频处理进度通知
- [ ] 导出功能状态
- [ ] 网络连接状态
- [ ] 存储空间提醒
## UI 位置
- **Toast通知**: 屏幕右上角悬浮显示
- **消息中心按钮**: 顶部标题栏右侧，铃铛图标
- **消息中心面板**: 点击铃铛按钮弹出，右侧悬浮面板
## 注意事项
1. **⚠️ 避免无限循环**: 必须使用独立的选择器（如 `useShowSuccess()`），**绝对不要**使用返回对象的选择器（如 `useMessageActions()`），这会造成无限循环渲染
2. **性能**: 每个选择器都是独立的，不会创建新的对象引用
3. **持久化**: 消息仅在当前会话中保存
4. **限制**: 建议控制消息历史数量，避免内存过大
5. **可访问性**: 所有组件支持键盘导航和屏幕阅读器
### ❌ 错误用法
```typescript
// 这会造成无限循环！
const { showSuccess, showError } = useMessageActions();
```
### ✅ 正确用法
```typescript
// 使用独立选择器
const showSuccess = useShowSuccess();
const showError = useShowError();
```
## 自定义扩展
可以通过修改以下文件来扩展功能：
- `src/types/message.ts` - 消息类型定义
- `src/stores/messageStore.ts` - 状态管理逻辑
- `src/components/MessageCenter/` - UI组件
- `src/index.css` - 样式和动画

## 🌐 Internationalization Design
FlyCut Caption adopts componentized internationalization design, supporting flexible language pack management and real-time language switching. The component can automatically sync external language changes with internal UI components.
### Built-in Language Packs
```tsx
import { FlyCutCaption, zhCN, enUS } from '@flycut/caption-react'
// Use built-in Chinese language pack
<FlyCutCaption
config={{ language: 'zh' }}
locale={zhCN}
/>
// Use built-in English language pack
<FlyCutCaption
config={{ language: 'en' }}
locale={enUS}
/>
```
### Custom Language Packs
```tsx
import { FlyCutCaption, type FlyCutCaptionLocale } from '@flycut/caption-react'
// Create custom language pack (Japanese example)
const customJaJP: FlyCutCaptionLocale = {
common: {
loading: '読み込み中...',
error: 'エラー',
success: '成功',
confirm: '確認',
cancel: 'キャンセル',
ok: 'OK',
// ... more common translations
},
components: {
fileUpload: {
dragDropText: 'ビデオファイルをここにドラッグするか、クリックして選択',
selectFile: 'ファイルを選択',
supportedFormats: 'サポート形式：',
// ... more component translations
},
subtitleEditor: {
title: '字幕エディター',
addSubtitle: '字幕を追加',
deleteSelected: '選択項目を削除',
// ... more editor translations
},
// ... other component translations
},
messages: {
fileUpload: {
uploadSuccess: 'ファイルアップロード成功',
uploadFailed: 'ファイルアップロード失敗',
// ... more message translations
},
// ... other message translations
}
}
// Use custom language pack
<FlyCutCaption
config={{ language: 'ja' }}
locale={customJaJP}
/>
```
### Componentized Language Switching
The new componentized approach provides better language synchronization between external controls and internal components:
```tsx
import { useState } from 'react'
import { FlyCutCaption, zhCN, enUS, type FlyCutCaptionLocale } from '@flycut/caption-react'
function App() {
const [currentLanguage, setCurrentLanguage] = useState('zh')
const [currentLocale, setCurrentLocale] = useState<FlyCutCaptionLocale | undefined>(undefined)
const handleLanguageChange = (language: string) => {
console.log('Language switched to:', language)
setCurrentLanguage(language)
// Set corresponding language pack based on language
switch (language) {
case 'zh':
case 'zh-CN':
setCurrentLocale(zhCN)
break
case 'en':
case 'en-US':
setCurrentLocale(enUS)
break
case 'ja':
case 'ja-JP':
setCurrentLocale(customJaJP) // Custom Japanese pack
break
default:
setCurrentLocale(undefined) // Use default language pack
}
}
return (
<div className="min-h-screen bg-background">
<div className="container mx-auto py-8">
<h1 className="text-3xl font-bold text-center mb-8">

)
}
```
### Available Language Packs
| Language | Import | Description |
|----------|---------|-------------|
| Chinese (Simplified) | `zhCN` | 简体中文 |
| English (US) | `enUS` | English (United States) |
| Default | `defaultLocale` | Same as `zhCN` |
### Language Pack API
```tsx
// Import language pack utilities
import { LocaleProvider, useLocale, useTranslation } from '@flycut/caption-react'
// Use LocaleProvider for nested components
<LocaleProvider language="zh" locale={zhCN}>
<YourComponent />
</LocaleProvider>
// Access language pack context
const { t, setLanguage, registerLocale } = useLocale()
// Register custom language pack
registerLocale('fr', frenchLocale)
// Programmatic language switching
setLanguage('fr')
```

```
### Next.js Integration
```tsx
// pages/editor.tsx
import dynamic from 'next/dynamic'
import { useState } from 'react'
// Dynamically import to avoid SSR issues
const FlyCutCaption = dynamic(
() => import('@flycut/caption-react').then(mod => mod.FlyCutCaption),
{ ssr: false }
)
export default function EditorPage() {
return (
<div style={{ height: '100vh' }}>
<FlyCutCaption
config={{
theme: 'auto',
language: 'zh'
}}
onVideoProcessed={(blob, filename) => {
// Handle video processing result
const url = URL.createObjectURL(blob)
window.open(url, '_blank')
}}
/>
</div>
)
}
```
### Best Practices
1. **Always import styles**: The component requires CSS to work properly
2. **Handle errors gracefully**: Implement proper error boundaries and user feedback
3. **Optimize for performance**: Use dynamic imports for SSR applications
4. **Provide user feedback**: Show loading states and progress indicators
5. **Responsive design**: Ensure your container has appropriate height/width
6. **Accessibility**: The component includes ARIA labels and keyboard navigation
7. **Memory management**: Clean up blob URLs when components unmount

## 🌐 国际化设计
FlyCut Caption 采用组件化国际化设计，支持灵活的语言包管理和实时语言切换。组件能够自动同步外部语言变化与内部 UI 组件。
### 内置语言包
```tsx
import { FlyCutCaption, zhCN, enUS } from '@flycut/caption-react'
// 使用内置中文语言包
<FlyCutCaption
config={{ language: 'zh' }}
locale={zhCN}
/>
// 使用内置英文语言包
<FlyCutCaption
config={{ language: 'en' }}
locale={enUS}
/>
```
### 自定义语言包
```tsx
import { FlyCutCaption, type FlyCutCaptionLocale } from '@flycut/caption-react'
// 创建自定义语言包（日语示例）
const customJaJP: FlyCutCaptionLocale = {
common: {
loading: '読み込み中...',
error: 'エラー',
success: '成功',
confirm: '確認',
cancel: 'キャンセル',
ok: 'OK',
// ... 更多通用翻译
},
components: {
fileUpload: {
dragDropText: 'ビデオファイルをここにドラッグするか、クリックして選択',
selectFile: 'ファイルを選択',
supportedFormats: 'サポート形式：',
// ... 更多组件翻译
},
subtitleEditor: {
title: '字幕エディター',
addSubtitle: '字幕を追加',
deleteSelected: '選択項目を削除',
// ... 更多编辑器翻译
},
// ... 其他组件翻译
},
messages: {
fileUpload: {
uploadSuccess: 'ファイルアップロード成功',
uploadFailed: 'ファイルアップロード失敗',
// ... 更多消息翻译
},
// ... 其他消息翻译
}
}
// 使用自定义语言包
<FlyCutCaption
config={{ language: 'ja' }}
locale={customJaJP}
/>
```
### 组件化语言切换
新的组件化方法提供外部控制与内部组件间更好的语言同步：
```tsx
import { useState } from 'react'
import { FlyCutCaption, zhCN, enUS, type FlyCutCaptionLocale } from '@flycut/caption-react'
function App() {
const [currentLanguage, setCurrentLanguage] = useState('zh')
const [currentLocale, setCurrentLocale] = useState<FlyCutCaptionLocale | undefined>(undefined)
const handleLanguageChange = (language: string) => {
console.log('语言已切换为:', language)
setCurrentLanguage(language)
// 根据语言设置相应的语言包
switch (language) {
case 'zh':
case 'zh-CN':
setCurrentLocale(zhCN)
break
case 'en':
case 'en-US':
setCurrentLocale(enUS)
break
case 'ja':
case 'ja-JP':
setCurrentLocale(customJaJP) // 自定义日语包
break
default:
setCurrentLocale(undefined) // 使用默认语言包
}
}

### 可用语言包
| 语言 | 导入方式 | 描述 |
|----------|---------|-------------|
| 中文（简体） | `zhCN` | 简体中文 |
| 英文（美式） | `enUS` | English (United States) |
| 默认 | `defaultLocale` | 与 `zhCN` 相同 |
### 语言包 API
```tsx
// 导入语言包工具
import { LocaleProvider, useLocale, useTranslation } from '@flycut/caption-react'
// 为嵌套组件使用 LocaleProvider
<LocaleProvider language="zh" locale={zhCN}>
<YourComponent />
</LocaleProvider>
// 访问语言包上下文
const { t, setLanguage, registerLocale } = useLocale()
// 注册自定义语言包
registerLocale('fr', frenchLocale)
// 程序化语言切换
setLanguage('fr')
```
📚 **详细国际化指南**：查看 [INTERNATIONALIZATION.md](./INTERNATIONALIZATION.md) 了解完整的语言包、自定义本地化和高级国际化功能文档。
## 📚 使用指南
### 1. 安装与设置
```bash
# 安装包
npm install @flycut/caption-react
# TypeScript 项目无需额外类型包
# 类型定义已包含在内
```
### 2. 导入样式
组件需要 CSS 样式才能正常工作：
```tsx
import '@flycut/caption-react/styles'
// 或指定 CSS 文件
import '@flycut/caption-react/dist/caption-react.css'
```
### 3. 基础集成
```tsx
import { FlyCutCaption } from '@flycut/caption-react'
import '@flycut/caption-react/styles'
function VideoEditor() {
return (
<div className="video-editor-container">
<FlyCutCaption />
</div>
)
}
```
### 4. 事件处理
```tsx
import { FlyCutCaption } from '@flycut/caption-react'
function VideoEditorWithEvents() {
const handleFileSelected = (file: File) => {
console.log('选择的文件:', file.name, file.size)
}
const handleSubtitleGenerated = (subtitles: SubtitleChunk[]) => {
console.log('生成的字幕:', subtitles.length)
// 保存字幕到后端
saveSubtitles(subtitles)
}
const handleVideoProcessed = (blob: Blob, filename: string) => {
// 处理生成的视频
const url = URL.createObjectURL(blob)
// 下载或上传到服务器
downloadFile(url, filename)
}
const handleError = (error: Error) => {
// 优雅处理错误
console.error('FlyCut Caption 错误:', error)
showErrorNotification(error.message)
}
return (
<FlyCutCaption
onFileSelected={handleFileSelected}
onSubtitleGenerated={handleSubtitleGenerated}
onVideoProcessed={handleVideoProcessed}
onError={handleError}
/>
)
}
```
### 5. 配置选项
```tsx
import { FlyCutCaption } from '@flycut/caption-react'
function ConfiguredEditor() {
const config = {
// 主题设置
theme: 'dark' as const,
// 语言设置
language: 'zh-CN',
asrLanguage: 'zh',
// 功能开关
enableDragDrop: true,
enableExport: true,
enableVideoProcessing: true,
enableThemeToggle: true,
enableLanguageSelector: true,
// 文件限制
maxFileSize: 1000, // 1GB
supportedFormats: ['mp4', 'webm', 'mov']
}
return (
<FlyCutCaption config={config} />
)
}
```
### 6. 自定义样式
```tsx
import { FlyCutCaption } from '@flycut/caption-react'
import './custom-styles.css'
function StyledEditor() {
return (
<FlyCutCaption
className="my-custom-editor"
style={{
borderRadius: '8px',
boxShadow: '0 4px 6px rgba(0, 0, 0, 0.1)'
}}
/>
)
}
```
```css
/* custom-styles.css */
.my-custom-editor {
--flycut-primary: #10b981;
--flycut-border-radius: 12px;
}
.my-custom-editor .subtitle-item {

import React, { useState, useCallback } from 'react'
import { FlyCutCaption, zhCN, enUS, type FlyCutCaptionLocale } from '@flycut/caption-react'
import '@flycut/caption-react/styles'
function VideoEditorApp() {
const [language, setLanguage] = useState<'zh' | 'en'>('zh')
const [subtitles, setSubtitles] = useState([])
const [isProcessing, setIsProcessing] = useState(false)
const locale = language === 'zh' ? zhCN : enUS
const handleLanguageChange = useCallback((newLang: string) => {
setLanguage(newLang as 'zh' | 'en')
}, [])
const handleSubtitleGenerated = useCallback((newSubtitles) => {
setSubtitles(newSubtitles)
// 自动保存到本地存储
localStorage.setItem('flycut-subtitles', JSON.stringify(newSubtitles))
}, [])
const handleProgress = useCallback((stage: string, progress: number) => {
setIsProcessing(progress < 100)
}, [])

pub mime_type: Option<String>,
pub created: Option<SystemTime>,
pub modified: Option<SystemTime>,
}
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct FileFilter {
pub name: String,
pub extensions: Vec<String>,
}
#[derive(Debug, thiserror::Error, Serialize)]
pub enum FileError {
#[error("文件不存在: {path}")]
FileNotFound { path: String },
#[error("权限不足: {message}")]
PermissionDenied { message: String },
#[error("IO 错误: {message}")]
IoError { message: String },

```
## 🔄 事件系统设计
### 事件类型定义
```rust
// src-tauri/src/events.rs
#[derive(Debug, Clone, Serialize)]
#[serde(tag = "type")]
pub enum AppEvent {
// ASR 相关事件
TranscriptionStarted { task_id: String },
TranscriptionProgress { progress: TranscriptionProgress },
TranscriptionCompleted { task_id: String, result: TranscriptResult },
TranscriptionFailed { task_id: String, error: String },
// 视频处理相关事件
VideoProcessingStarted { task_id: String },
VideoProcessingProgress { progress: VideoProcessingProgress },
VideoProcessingCompleted { task_id: String, output_path: String },
VideoProcessingFailed { task_id: String, error: String },
// 模型下载相关事件
ModelDownloadStarted { model_name: String },
ModelDownloadProgress { model_name: String, progress: f32 },
ModelDownloadCompleted { model_name: String },
ModelDownloadFailed { model_name: String, error: String },
// 系统相关事件
SystemResourceWarning { message: String },
ApplicationUpdated { version: String },
}
```
### 前端事件监听
```typescript
// src/services/eventService.ts
import { listen, UnlistenFn } from '@tauri-apps/api/event';
export class EventService {
private static listeners: Map<string, UnlistenFn> = new Map();
static async onTranscriptionProgress(
callback: (progress: TranscriptionProgress) => void
): Promise<string> {
const unlisten = await listen('transcription-progress', (event) => {
callback(event.payload as TranscriptionProgress);
});
const listenerId = `transcription-progress-${Date.now()}`;
this.listeners.set(listenerId, unlisten);
return listenerId;
}
static async onVideoProcessingProgress(
callback: (progress: VideoProcessingProgress) => void
): Promise<string> {
const unlisten = await listen('video-processing-progress', (event) => {
callback(event.payload as VideoProcessingProgress);
});
const listenerId = `video-processing-progress-${Date.now()}`;
this.listeners.set(listenerId, unlisten);
return listenerId;
}
static removeListener(listenerId: string): void {
const unlisten = this.listeners.get(listenerId);
if (unlisten) {
unlisten();
this.listeners.delete(listenerId);
}
}
static removeAllListeners(): void {
for (const [id, unlisten] of this.listeners) {
unlisten();
}
this.listeners.clear();
}
}
```
## 🛡️ 错误处理策略
### 统一错误类型
```rust
// src-tauri/src/error.rs
use serde::Serialize;
use thiserror::Error;
#[derive(Error, Debug, Serialize)]
pub enum AppError {
#[error(transparent)]
File(#[from] FileError),
#[error(transparent)]
ASR(#[from] ASRError),
#[error(transparent)]
Video(#[from] VideoError),
#[error(transparent)]
System(#[from] SystemError),
#[error("未知错误: {message}")]
Unknown { message: String },
}
impl From<AppError> for String {
fn from(error: AppError) -> Self {
error.to_string()
}
}
```
### 前端错误处理
```typescript
// src/utils/errorHandler.ts
export interface AppError {
type: 'file' | 'asr' | 'video' | 'system' | 'unknown';
message: string;
details?: Record<string, any>;
}
export function parseError(error: string): AppError {
try {
const parsed = JSON.parse(error);
return {
type: parsed.type || 'unknown',
message: parsed.message || error,
details: parsed.details,
};
} catch {
return {
type: 'unknown',
message: error,
};
}
}
export function handleAPIError(error: string): void {
const appError = parseError(error);
// 根据错误类型执行不同的处理逻辑
switch (appError.type) {
case 'file':
console.error('File error:', appError.message);
// 显示文件相关错误提示
break;
case 'asr':
console.error('ASR error:', appError.message);
// 显示 ASR 相关错误提示
break;
case 'video':
console.error('Video error:', appError.message);
// 显示视频处理错误提示
break;
default:
console.error('Unknown error:', appError.message);
}
}
```

}
// 执行转录
let result = self.context.full(params, audio_samples)?;
// 转换为前端需要的格式
Ok(self.convert_to_transcript_result(result))
}
}
```
#### 2. 视频处理服务
```rust
// src-tauri/src/services/ffmpeg_service.rs
use std::process::Command;
pub struct FFmpegService {
ffmpeg_path: PathBuf,
}
impl FFmpegService {
pub fn new(ffmpeg_path: PathBuf) -> Self {
Self { ffmpeg_path }
}
pub async fn export_video(
&self,
input: &str,
segments: &[TimeSegment],
output: &str,
quality: VideoQuality,

Err(FFmpegError::ProcessingFailed(
String::from_utf8_lossy(&output.stderr).to_string()
))
}
}
fn build_segment_filter(&self, segments: &[TimeSegment]) -> String {
// 构建复杂的 FFmpeg 过滤器
// 例如: "select='between(t,0,10)+between(t,15,25)',setpts=N/FRAME_RATE/TB"
segments.iter()
.map(|seg| format!("between(t,{},{})", seg.start, seg.end))
.collect::<Vec<_>>()
.join("+")
}
}
```
### Tauri 命令接口

.await
.map_err(|e| e.to_string())
}
#[tauri::command]
pub async fn get_available_models() -> Result<Vec<ModelInfo>, String> {

}
```
## 🔄 前后端通信
### IPC 通信模式
```typescript
// 前端调用后端
import { invoke } from '@tauri-apps/api/tauri';
// ASR 转录
const result = await invoke<TranscriptResult>('transcribe_audio', {

window.emit("transcription-progress", ProgressPayload {
current: 50,
total: 100,
message: "Processing audio...".to_string(),
}).unwrap();
// 继续处理...
Ok(result)

// src-tauri/src/utils/config.rs
use serde::{Deserialize, Serialize};
#[derive(Serialize, Deserialize, Default)]
pub struct AppConfig {
pub preferred_model: String,
pub output_quality: String,
pub cache_dir: PathBuf,
pub hardware_acceleration: bool,
}
impl AppConfig {
pub fn load() -> Result<Self, ConfigError> {
let config_path = Self::config_path()?;
if config_path.exists() {
let content = std::fs::read_to_string(config_path)?;
Ok(serde_json::from_str(&content)?)
} else {
Ok(Self::default())
}
}
pub fn save(&self) -> Result<(), ConfigError> {
let config_path = Self::config_path()?;
let content = serde_json::to_string_pretty(self)?;
std::fs::write(config_path, content)?;
Ok(())
}
}
```
## 🔧 性能优化策略
### 1. 并发处理
```rust
// 使用 Tokio 异步运行时
use tokio::task;
pub async fn process_multiple_segments(
segments: Vec<TimeSegment>
) -> Result<Vec<ProcessedSegment>, ProcessingError> {
let tasks = segments.into_iter()
.map(|segment| {
task::spawn(async move {
process_single_segment(segment).await
})
})
.collect::<Vec<_>>();
let results = futures::future::try_join_all(tasks).await?;
Ok(results)
}
```
### 2. 内存管理
```rust
// 流式处理大文件
use tokio::fs::File;
use tokio::io::{AsyncReadExt, BufReader};
pub async fn process_large_video(
input_path: &str,
chunk_size: usize,
) -> Result<(), ProcessingError> {
let file = File::open(input_path).await?;
let mut reader = BufReader::new(file);
let mut buffer = vec![0; chunk_size];
while reader.read_exact(&mut buffer).await.is_ok() {
// 分块处理视频数据
process_chunk(&buffer).await?;
}
Ok(())
}
```
### 3. 缓存策略
```rust
use std::collections::HashMap;
use tokio::sync::RwLock;
pub struct CacheService {
cache: RwLock<HashMap<String, CachedResult>>,
max_size: usize,
}
impl CacheService {
pub async fn get_or_compute<T, F>(
&self,
key: &str,
compute_fn: F,
) -> Result<T, CacheError>
where
F: Future<Output = Result<T, CacheError>>,
T: Clone + Serialize + DeserializeOwned,
{
// 先检查缓存
{
let cache = self.cache.read().await;
if let Some(cached) = cache.get(key) {
if !cached.is_expired() {
return Ok(cached.data.clone());
}
}
}
// 计算结果
let result = compute_fn.await?;
// 存入缓存
{
let mut cache = self.cache.write().await;
cache.insert(key.to_string(), CachedResult::new(result.clone()));
}
Ok(result)
}
}
```
## 🚀 部署架构

```
### 自动更新机制
```rust
// src-tauri/src/commands/update.rs
use tauri_plugin_updater::UpdaterExt;
#[tauri::command]
pub async fn check_for_updates(app: tauri::AppHandle) -> Result<UpdateInfo, String> {
let updater = app.updater();
match updater.check().await {
Ok(Some(update)) => {
Ok(UpdateInfo {
available: true,
version: update.version,
notes: update.body.unwrap_or_default(),
download_url: update.download_url,
})
}
Ok(None) => Ok(UpdateInfo::no_update()),
Err(e) => Err(e.to_string()),
}
}
#[tauri::command]
pub async fn install_update(app: tauri::AppHandle) -> Result<(), String> {
let updater = app.updater();
if let Some(update) = updater.check().await.map_err(|e| e.to_string())? {
update.download_and_install().await.map_err(|e| e.to_string())?;
}
Ok(())
}
```
这个架构设计确保了：
- **前端零改动**: 现有 React 代码完全保留
- **高性能**: 本地处理 + 硬件加速
- **可维护性**: 清晰的模块化设计
- **可扩展性**: 插件化的服务架构
- **用户体验**: 原生应用级别的体验

// scripts/release.js
const { execSync } = require('child_process');
const fs = require('fs');
const path = require('path');
const version = process.env.npm_package_version;
const platforms = ['windows', 'macos', 'linux'];
async function release() {
console.log(`Releasing FlyCut Caption v${version}...`);
try {
// 构建所有平台
console.log('Building for all platforms...');
execSync('pnpm build:all', { stdio: 'inherit' });
// 签名二进制文件
if (process.platform === 'win32') {
execSync('pnpm sign:windows', { stdio: 'inherit' });
} else if (process.platform === 'darwin') {
execSync('pnpm sign:macos', { stdio: 'inherit' });
}
// 上传到发布服务器
console.log('Uploading releases...');
platforms.forEach(platform => {
const releaseDir = `src-tauri/target/release/bundle/${platform}`;
if (fs.existsSync(releaseDir)) {
// 上传逻辑
console.log(`Uploaded ${platform} release`);
}
});
// 创建 GitHub Release
console.log('Creating GitHub release...');
execSync(`gh release create v${version} --generate-notes`, { stdio: 'inherit' });
console.log('Release completed successfully!');
} catch (error) {
console.error('Release failed:', error);
process.exit(1);
}
}
release();
```

#### 1.1 Tauri 项目初始化
```bash
# 1. 安装 Tauri CLI
cargo install tauri-cli
# 2. 初始化 Tauri 项目
pnpm tauri init
```
#### 1.2 项目配置
**tauri.conf.json 配置**:
```json
{
"package": {
"productName": "FlyCut Caption",
"version": "1.0.0"
},
"build": {
"distDir": "../dist",
"devPath": "http://localhost:5175",
"beforeDevCommand": "pnpm dev",

}
]
}
}
```
#### 1.3 基础文件操作迁移
**前端 API 适配**:
```typescript
// src/services/fileService.ts
import { invoke } from '@tauri-apps/api/tauri';
import { open } from '@tauri-apps/api/dialog';
// 文件选择 (替换 HTML input file)
export async function selectVideoFile(): Promise<string | null> {
const selected = await open({
multiple: false,
filters: [{
name: 'Video',
extensions: ['mp4', 'mov', 'avi', 'mkv', 'webm']
}]
});
return typeof selected === 'string' ? selected : null;
}
// 文件保存
export async function saveVideo(content: Uint8Array): Promise<string | null> {
return await invoke('save_video_file', { content });
}
```
**Rust 后端实现**:
```rust
// src-tauri/src/commands/file.rs
use tauri::{command, api::dialog::FileDialogBuilder};
use std::path::PathBuf;
#[command]
pub async fn save_video_file(
content: Vec<u8>,
app_handle: tauri::AppHandle,
) -> Result<String, String> {
let save_path = FileDialogBuilder::new()
.set_title("保存视频")
.add_filter("视频文件", &["mp4", "mov"])
.save_file()
.await;
if let Some(path) = save_path {
std::fs::write(&path, content)
.map_err(|e| format!("保存失败: {}", e))?;
Ok(path.to_string_lossy().to_string())
} else {
Err("用户取消保存".to_string())
}
}
#[command]
pub async fn get_file_info(path: String) -> Result<FileInfo, String> {
let metadata = std::fs::metadata(&path)
.map_err(|e| format!("获取文件信息失败: {}", e))?;
Ok(FileInfo {
size: metadata.len(),
modified: metadata.modified().unwrap_or(SystemTime::UNIX_EPOCH),
path,
})
}
```
### Phase 2: AI 本地化 (1-2 周)
#### 2.1 Whisper.cpp 集成
**Cargo.toml 依赖**:
```toml
[dependencies]
whisper-rs = "0.10"
tokio = { version = "1.0", features = ["full"] }
serde = { version = "1.0", features = ["derive"] }
```

// src-tauri/src/services/whisper_service.rs
use whisper_rs::{FullParams, SamplingStrategy, WhisperContext, WhisperContextParameters};
use std::path::PathBuf;
use tokio::sync::Mutex;
pub struct WhisperService {
context: Mutex<WhisperContext>,
model_path: PathBuf,
}
impl WhisperService {
pub fn new(model_path: PathBuf) -> Result<Self, Box<dyn std::error::Error>> {
let ctx_params = WhisperContextParameters::default();
let context = WhisperContext::new_with_params(&model_path, ctx_params)?;
Ok(Self {
context: Mutex::new(context),
model_path,
})
}
pub async fn transcribe(
&self,
audio_data: Vec<f32>,
language: Option<String>,
progress_callback: Option<fn(i32)>,
) -> Result<TranscriptResult, Box<dyn std::error::Error>> {
let context = self.context.lock().await;
let mut params = FullParams::new(SamplingStrategy::Greedy { best_of: 1 });
// 设置语言
if let Some(lang) = language {
params.set_language(Some(&lang));
}
// 设置其他参数
params.set_translate(false);
params.set_print_special(false);
params.set_print_progress(false);
params.set_print_realtime(false);
params.set_print_timestamps(true);
// 设置进度回调
if let Some(callback) = progress_callback {
params.set_progress_callback_safe(callback);
}
// 执行转录
context.full(params, &audio_data)?;
// 获取结果
let num_segments = context.full_n_segments()?;
let mut chunks = Vec::new();
for i in 0..num_segments {
let start_timestamp = context.full_get_segment_t0(i)? as f64 / 100.0;
let end_timestamp = context.full_get_segment_t1(i)? as f64 / 100.0;
let text = context.full_get_segment_text(i)?;
chunks.push(SubtitleChunk {
id: format!("chunk_{}", i),
timestamp: [start_timestamp, end_timestamp],

});
}
Ok(TranscriptResult {
language: language.unwrap_or_default(),
chunks,
})
}
}
```

model_name
);
let response = reqwest::get(&url).await?;
let bytes = response.bytes().await?;
fs::create_dir_all(&self.models_dir).await?;
let model_path = self.models_dir.join(format!("{}.bin", model_name));
fs::write(model_path, bytes).await?;
Ok(())
}
pub fn list_available_models() -> Vec<ModelInfo> {
vec![
ModelInfo { name: "tiny".to_string(), size: "39 MB".to_string(), languages: "多语言".to_string() },

ModelInfo { name: "large".to_string(), size: "1550 MB".to_string(), languages: "多语言".to_string() },
]
}
}
```

// 调用 Tauri 后端
const result = await invoke('transcribe_audio', {
audioData: Array.from(audioData),
language,
model
});
return result as TranscriptResult;

const channelData = audioBuffer.getChannelData(0);
const view = new Float32Array(buffer);
channelData.set(view);
return channelData;

# 语言选择器组件
提供两种语言选择器组件，用于 Whisper ASR 语言选择。
## 组件
### 1. LanguageSelector - 基础语言选择器
简单的下拉选择器，适用于快速选择。
```tsx
import { LanguageSelector } from '@/components/LanguageSelector';
<LanguageSelector
language={language}
onLanguageChange={(lang) => setLanguage(lang)}
disabled={false}
showLabel={true}
size="md"
/>
```
**Props:**
- `language: string` - 当前选中的语言代码
- `onLanguageChange: (language: string) => void` - 语言变化回调
- `disabled?: boolean` - 是否禁用
- `className?: string` - 自定义样式类
- `showLabel?: boolean` - 是否显示标签（默认 true）
- `size?: 'sm' | 'md' | 'lg'` - 组件大小
### 2. AdvancedLanguageSelector - 高级语言选择器
带搜索功能的高级选择器，支持所有 Whisper 语言。
```tsx
import { AdvancedLanguageSelector } from '@/components/LanguageSelector';
<AdvancedLanguageSelector
language={language}
onLanguageChange={(lang) => setLanguage(lang)}
disabled={false}
placeholder="搜索语言..."
/>
```
**Props:**
- `language: string` - 当前选中的语言代码
- `onLanguageChange: (language: string) => void` - 语言变化回调
- `disabled?: boolean` - 是否禁用
- `className?: string` - 自定义样式类
- `placeholder?: string` - 搜索框占位符
## 特性

## 使用场景
### 在 ASR 面板中使用
```tsx
// 快速选择（显示在主界面）
<LanguageSelector
language={language}
onLanguageChange={handleLanguageChange}
disabled={isLoading}
size="sm"
/>
// 高级选择（显示在设置面板）
<AdvancedLanguageSelector
language={language}
onLanguageChange={handleLanguageChange}
disabled={isLoading}
placeholder="搜索支持的语言..."
/>
```
## 样式定制
两个组件都支持通过 `className` 进行样式定制，并且完全兼容 Tailwind CSS 的深色模式。
```tsx
<LanguageSelector
className="w-48" // 自定义宽度
// 其他 props...
/>
```
